FEED DEVICE FOR WlRE-WEAVING MACHINES.

SPECIFICATION forming part of Letters Patent No. 403,109, dated May 14, 1889.

Application filed March 5, 1889. Serial No. 301,946. (No model.)

To all whom it may concern.-

Be it known that I, OZELLO R. HUNT,a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Feed Devices for Wire-Weaving Machines, of which the following is a specification.

My invention relates to machines for bending or coiling wire to form wire fabrics, and more particularly to machines for making woven-wire mattresses.

In machines of this class the rolls for feed ing the Wire become Worn and require turning down and adjusting from time to time, and as they are usually operated by gearwheels attached to their ends or to their shafts adjustment beyond very narrow limits is precluded by the unyielding character of the gearing. To overcome this difficulty by providing different means for rotating the rolls and devices for adjusting their relative positions is the object of this invention. This object is accomplished by the devices illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a portion of a wire-weaving machine containing my improvements, and Fig. 2 is an end view of the same, the pulleys and feed-rolls being removed and the position of the latter being shown by dotted circles.

In said drawings, Aindicates the machineframe.

B is the driving shaft of the machine driven by means of a belt on the pulley C. On the end of the shaft B is carried an ordinary grooved feed-roll, D, and in engage ment with it is a similar roll, D, carried on and secured to the hub e of a pulley, E, that turns on a non-rotating shaft, B. A driven shaft, B mounted on the top of the frame A, carries pulleys F and G. The proper rotation is given the feed-roll D by a belt on the pulley F with a pulley, O, on the shaft B.

The shaft B is loose in a slot, a, in the frame A, and is subjected to the force of a spring, H, (preferably a rubber spring,) to give a proper pressure on the wire between the feed-rolls. The spring-pressure may be regulated by means of a set-screw, h, bearing upon the spring from its upper side. The opposite end of the shaft B is held by a bolt, I, passing through a slot, 0,, in a projecting portion, o of the machine-frame, so that the end of the shaft can be adjusted to positions above or below the horizontal line to increase or lessen the pressure of the upper roller upon the lower, as may be required to effect the desired feed. Thus any wear or lessening of the size of the rolls D D byturning clown can be compensated for by adjustment of the set-screwhorbolt I, or both, when required, so that the necessary friction between the rolls can at all times be maintained to insure a proper feeding of the wire.

Having described my invention, what I claim 1s 1. In a wire-weaving machine, a rotating and a non-rotating shaft, the latterbeing supported by an adjustable pivot and having a spring tension in the direction of the former shaft, and feed-rolls, one of which is rotated by the former shaft and the other by a pulley on the latter shaft, substantially as set forth.

2. In a wire-weaving machine, a frame, a driving-shaft and pulleys, a driven shaft and pulleys, a non-rotating shaft sliding in a slot in said frame, an adjustable pivotal support therefor, and an adjustable spring whose tension thereon is in the direction of the drivingshaft, a feed-roll and pulley thereon rotated by belting from the driven shaft, and a roll rotated by the driving-shaft, substantially as set forth.
